My dog has blood in his stool but is energetic. Should I worry?

Updated On September 23rd, 2025

Pet's info: Dog | Boston Terrier | Male | neutered | 9 years and 11 months old | 28 lbs

My 9 year old Boston has blood in his stool. It’s not diarrhea but it is softer than normal. The blood seems to be normal blood and not a red colored mucus. He’s super energetic, eats and drinks normally and that hasn’t changed at all.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Rowdy! Blood in the stool indicates inflammation in the colon usually though since Rowdy is older a tumor in the rectum is also possible. Cause could be: intestinal parasites, viral or bacterial infections, he ate something gross outside upsetting his GI tract, reaction to a new treat/food/table scraps, food allergy/reaction, pancreatitis, clotting or platelet disorders. You can start a probiotic like Purina Fortiflora and get him on a bland diet of boiled chicken or hamburger with rice until the stool normalizes then gradually get him back on his dog food. If the blood persists then he should be examined by your Vet. I wish Rowdy the best!
